Inebriated to incoherency. Worse than shit-faced because you can't even say shit-faced anymore. Above and beyond, normal drunkenness, those who are shi'pay are likely to end up arrested, swimming in their own bodily wastes, getting tossed out of parties, losing all of their gear including clothing, having Sharpie tattoos drawn on them by total strangers and waking up with a hang-over bad enough to ask for Dr. Kevorkian and no recollection of the previous night's idiocy.

Man, I was so loaded last night. I woke up in a bus station, no pants, covered in invitations to hobos to take my stuff and the taste of Taco Bell and feet in my mouth. Definitely shi'pay.
